The following report of Superintendent
Webster, of the Plttsburg Con. Gold M.
Co., appears in the London Mining Jour.
nal. The mines were recently purchased
by an English company, and the report
Is interesting, as it shows the condition
OF a mine which English capitalists con-

am much gratifed to announce that
considerable improvements have been
made in the mining and milling depart
ments since my report. AS shall have

but the usual good progress has been
made-Air Shaft: The lode has again in

4 feet wide; the ore is not so strongly
charged with pyrites, aud assays about
$ll per ton, but expect an early i'm
proyement in the quality Of quartz as the
strata is veIy congenial, being composed
of soft clay, slate and porphyry. There
is now good hanging wall, and for the
last 6 feet no timber has been required
No. Level: L am pleased to say that
we have intersectei fine lode III this
level, which measures about Al feet wide,
and assays to-day SIS per ton; it is a
very promising lode. and very likely to
improve in quality as the level is ad-
vsnced. There is considerable water is

Slopes: The Slopes in floor of No. 3
level east aud west of No. Wine con-
tinue to yield splendid ore, the assays
for the past week having averaged $63
per ton, and the samples assayed from
the slopes in roof of No. 4 level west of
No. 3 Wine have averaged go per ton.
In the former slopes the lode 10 now

same during the last two days have aver

inform you that we have several thou.

that when We get NO 8. level advanced
to this point our average yield will not
be under $40 to $50 per ton.
Mill: We have miIled during the past
week "a tons, which have produced suf-
ticient smslgam to yield 81 600. or SIS

time have averaged Sl4 SO, making a
total of S32 80 per ten. During the last
three days we have crushed ore pIinci.

turn out considerable bullion in a few
weeks, but on account OF its scarcity we
cannot mill much over Ii tons per day.

engineer erecting the new machinery and
we find it will not be necessary to remove
our boiler and mills from here for another
fortnight, so have decided to continue
milling for that period. Il is probable
that the new machinery vii. not be ready
to start before the middle Of November,
although all possible haste is being made.
The tramway will be completed some
time before the mills are ready to start.
